Background: Traits of non-dominant mixed-forest tree species and their synergies for successful co-occurrence in
monodominant Gilbertiodendron dewevrei forest have not yet been investigated. Here we compared the tree species
diversity of the monodominant forest with its adjacent mixed forest and then determined which fitness proxies and life
history traits of the mixed-forest tree species were most associated with successful co-existence in the monodominant
forest.
Methodology/Principal Findings: We sampled all trees (diameter in breast height [dbh]$10 cm) within 661 ha
topographically homogenous areas of intact central African forest in SE Cameroon, three independent patches of G.
dewevrei-dominated forest and three adjacent areas (450–800 m apart). Monodominant G. dewevrei forest had lower
sample-controlled species richness, species density and population density than its adjacent mixed forest in terms of stems
with dbh$10 cm. Analysis of a suite of population-level characteristics, such as relative abundance and geographical
distribution, and traits such as wood density, height, diameter at breast height, fruit/seed dispersal mechanism and light
requirement–revealed after controlling for phylogeny, species that co-occur with G. dewevrei tend to have higher
abundance in adjacent mixed forest, higher wood density and a lower light requirement.
Conclusions/Significance: Our results suggest that certain traits (wood density and light requirement) and population-level
characteristics (relative abundance) may increase the invasibility of a tree species into a tropical closed-canopy system. Such
knowledge may assist in the pre-emptive identification of invasive tree species.

The genus Sericanthe was established and its species were revised 30 years ago by one of the authors. Intensive recent botanical collecting in Lower Guinea (mainly southern Cameroon, Equatorial Guinea and Gabon) has made a reconsideration of species in this area necessary. Revision of the newly collected Lower Guinean herbarium specimens of Sericanthe (twice as many as were available at the time of the first revision) has brought four new species to light, namely S. gabonensis and S. mpassa from Gabon, S. lowryana from Cameroon and S. rabia from Cameroon and Gabon. Distributional data are much augmented, and distributional maps of all species from the area are provided. Four species were reported to be newly recorded for at least one country. The occurrence of the novelties in the main diversity centre of the genus is discussed in the context of the chorology of the entire genus Sericanthe. A first estimation of the conservation status for the new species is given. A synopsis of the genus Sericanthe in Lower Guinea with a taxonomic key is provided.
